Just wanted to let everyone know the *aggressive* units are back in stock, so both styles should be in stock and available. As are the rear diff/suspension covers and the OEM exhaust cover

. We are working on coming up with a Type 80 kit that will be added at checkout for those customers as well. I would expect something around the first of the year (hopeful thinking).

I've spent the past few weekends doing some further testing to continually prove our CFD does in fact translate to real world results. We have had some warranted skepticism of if the air is staying attached to the rear up-turned lip that has become a staple for our diffusers. Our CFD showed that it does stay attached but CFD is just a tool, a simulation that can deviate from real world results. This applies to wind tunnels as well, can't stress that real world results can deviate from wind tunnel testing as well!

So what did we come up with? We decided we could tuft test the diffuser on an open stretch of road. We are in the process of developing an educational video detailing what we found. Below is a preliminary picture of the diffuser with the tufts attached. This was actually a lot of fun, more fun than I was anticipating, but also quite time consuming.

Looking forward to posting the video in a few weeks when I find time to finish it up
